Specification of Letters Patent.

Patented Jan. 30,1912.

1911. Serial No. 616,243.

To all whom it may concern Be it known that I, JOHN NYE, a citizen of the United States, residing at Montpelier,

the county of Williams and State of Ohio, have invented certain new and useful Improvements in Window-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to same, reference being had to the accompanying drawings, and to the letters and figures part .of this specification.

Thi invention relates to improvements in roller window screens and it has for its object an improved construction of unitary nature which may be set up and removed or repaired with great facility and which may be applied to windows without regard to heading orblind stops.

tures of detail improvement, viz., an imof assemblage of the weather shield, an improvement 1n the connection between the sheet of'screen netting and the spring wound of the arrangement as a whole and other features of detail improvement which will appear as the description proceeds.

Embodiments of the invention are illustrat'ed in the accompanying drawings wherein- Figure 1 is an elevation, partly in section of a screen construction conforming-to the invention; Fig. 2 is a vertical section on the line 2--2 ofFig. 1; Fig. 3 is a horizontal section on the line 3-3 of Fig. 2; Fig. 4 is anenlarged vertical cross-section partly in elevation, on the line 4-4 of Fig. 2; Fig. 5 is a detail end elevation of the casing which between the spring roller and the sheet of screen netting; Fig. 7 is an elevation of the upper portion of the frame of the screen;

Fig. 8 is a detail plan view of the connections between the spring roller and the sheet of screen netting; Fig. 9 is a detail sectional view showing a locking bolt and its adjuncts by which the screen is fixed at any desired elevation; Fig. 10 is a front elevation of the same;Fig. 11 is an elevation, partly in section showing another form of the improved screen which is especially adapted for double windows; Fig. 12 is a vertical sectional View on the line 12-12 of Fig. 11; Fig. 13 is an enlarged horizontal sectionalview on the line 13-13 of Fig. 12; Fig. 14 is a cross section through the spring roller.

I Similar characters of reference designate corresponding parts throughout the several vlews.

By reference to Figs. 1, 2 and 3, it will be seen that the screen and its adjuncts are assembled with relation to a rectangular frame which may be of suitably ornamental character and which comprises an upper bar 1, side bars 2, and a-lower bar 3.

The screen proper includes a spring wound roller, designated generally by the numeral 4, and a sheet of screen netting 5 which is associated with the roller 4. The roller is inclosed in a protecting casing which includes a weather guard 6,end plates 7, and a bottom plate 8. The weather guard 6 consists of a sheet metal wall whlch is curved in cross-section as shown in Figs. 2 and 6, and which has its cross sectionally curved portion continued tangentially from its upper side, as at 9." The end plates 7 are fashioned to conformably fit within the guard 6 and are secured within the end portions of said guard, as by screws 10. The

bottom plate 8 is secured as by screws 11 to near the block 14:. A pin 16 projects axially from the block 14 and a pin 18 projects axially from the block 14*. The pins 16 and 18 constitute trunnions for the roller and have their bearings in the end plates 7 The pin 18 projects axially into the drum and has its inner end formed as a tenon to engage in an opening in the block 15. The pin 18' has fixed on its outer 9nd a handle 20 which is provided with ratchet teeth 19 for engagement by a pawl 21 pivoted on the adjacent end plate 7. The pin 18 serves to center the operating spring 22, which is of the flat coil type and has its ends associated with said rod and said drum, the said ends each having a hook formation and being engaged in recesses in the rod and the drum respectively. The pawl 21 engaging the teeth 19 serves to prevent backwardturning movement of the handle 19 and the pin 18 under, the tension of the spring 22 but permits the handle 19 and therewith the pin 18 to beturned forwardly through a suitable extent whenever it is necessary to increase the tension of the spring.

. The preferred means of connecting the sheet of netting 5 and the roller 4 includes a bar 24 and links 25. The bar at is co extensive. with the width of the sheet of netting and has an inturned flange which is clamped firmly upon the edge portion of the netting. The bar 24 is provided at equidistant points with openings 26 preferably having the shape of a crescent. Similar openings, as 27, are formed at corresponding points of the hollow drum. Each link 25 which is of somewhat less width than either of the crescent shaped openings aforesaid has at its ends inturned hooks 28, which engage,

over the straight edges of the respective openings 26 and 27. Three of these links are preferably employed.

The side bars 2 are provided at their upper ends with forwardly extending projections 29 which may be fashioned in simulation of cornice work and may be parts of the ornamental features of the frame. The projections are bridged by a bar 30 and have their inner sides cut away so as to afford grooves or recesses 31. The tangentially extended portion 9 of theweather guard 6 is of greater width than the guard so that, in effect, flanges 32 are provided which extend beyond the end plates 7. To organize the screen and the frame the flanges 32 are fitted in the grooves 31 and theend plates 7 are secured to the sidebars 2 as by screws 33 passing through extensions of said end plates.

The free edge portion of the screen netting which is drawn through the. slotted opening 13 is provided with a bar 34, the

ends of which are inturned as at '3@ and clamped upon the netting. The end portions 85 of the bar 34Lserve also as guides whereby the movements of the sheet of screen netting may be straight and regular, and for this purpose work in grooves or recesses 36 which are formed in strips 37 that are attached to the side bars 2.

The bar 34 provides also for the attachment at the opposite side of the netting, of a bar 38 which is disposed between the side bars 2 of the frame and which carries at its ends sliding spring pressed bolts. 39. The escutcheon plates of these bolts are attached to the exposed vertical face of the bar 38 and the finger pieces by which the bolts are retracted or projected pass through bayonet slots 40 in these escutcheon plates (Fig. 10). The side bars 2 each have their inner faces provided with a vertical row of openings 41 which are arranged at suitable intervals and are formed to receive the bolts 39.

For the purpose of excluding dust which might otherwise .pass through the slotted opening 13, the plate 8 has attached to its under face a suitable stri 42 which extends partially across the openlng 13 and with its edge bears against the sheet of screen netting.

In use, the screen frame, comprising the bars 1, 2 and 3 and to which the weather guard with the inclosed spring roller and sheet of netting has been fitted, is attached to the window casement or frame by screws or other suitable fastening. The entire screen is thus assembled in a unitary manner and itsassemblage involves no modification whatever of the window frame and is entirely independent of the spacing or thickness of the sash beads. In case the window frame should be slightly out of plumb, as not infrequently occurs the screen frame may be slightly sprung to meet the con dition and the straight travel of the sheet of netting is at the same time, assured, since the particular connection between the netting and the roller allows of such side play of the netting as may be necessary to insure its straight. travel, regardless of the spring ing of the screen frame.

Not only is the entire'arrangemcnt capable of attachment to and removal from the window frame in a-unitary fashion butthe weather guard and the spring roller and the netting are also capable of unitary attachment to and removal from the screen frame. The construction is therefore very readily accessible forthe purposes'of renewal and repair and it may be attached to or removed from a window frame in the quickest and most convenient manner. It will be observed that the arrangement is altogether self contained; that is to say, that it embodis in itself every element essential for its operation and thatit does not necessitate the use plates 7, has fitted of structu. ally independent adjuncts which must be applied to the window frame, nor in'fact any operations whatever in connection with the window frame except the attachment of the screen frame thereto.

The construction shown in Figs. 11, 1.2 and 13 is intended for use in connection with double windows and makes provision for duplicating the screens in a self contained organization. In this construction the casing which is provided by the weather guard (5, the bottom plate 8 and the end therein a centrally arranged partition plate 43. The spring rollers are arranged at each side of this partition plate and their t-runnions 16 are journaled therein. The window casing is shown as having an extended sill 4% which renders the use of the bar 3 unnecessary, the side bars 2 being imposed directly on this sill as shown in Fig. 12.

The modified construction includes also a centrally arranged vertical bar 45 which is associated with the bar 1 as by a rabbet joint 46 and which may be braced at the sill as by an angle plate 47. The bar 45 has its side faces formed with grooves or channels 36' corresponding to and complementing the channels 36 aforesaid in the function of guiding the sheets of netting; and also with openings 41 corresponding'to the openings ll aforesaid.

The modified construction is in other respects similar to the construction already described.
